Answer:
A. 30
Explanation:
Retinol is the chemical form of Vitamin A. It has a chemical formula of C20H30O.
It is processed when retinyl palmitate is broken down in the small intestine. Retinol helps in the proper regulation of eye cells hence a vital component in ensuring good eye sight.
It also helps in the neutralization of free radicals in the body and acts as an antioxidant which prevents cells of the body from ageing.
Answer:
D: When the acidity of a solution increases, the pH increases.
Explanation:
It is totally wrong to assert that when the acidity of a solution increases, the pH of the solution will increase
The right answer is that when the acidity of a solution increases, the pH value decreases.
- The pH scale records the level of acidity and basicity of a substance.
- It runs from 1 to 14
- From 7 to 14 signifies increasing basicity
- As the acidity of a substance increases, the pH value reduces.
- For acids 1 is the highest acidity levels.

Respuesta:
2 m
Explicación:
Paso 1: Información provista
- Volumen inicial (V₁): 100 mL
- Concentración inicial (C₁): 4 m
- Volumen final (V₂): 200 mL
- Concentración final (C₂): ?
Paso 2: Calcular la concentración de la solución final
Queremos perparar una concentración diluida a partir de una concentrada. Podemos calcular la concentración de la solución diluida usando la regla de dilución.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁ / V₂
C₂ = 4 m × 100 mL / 200 mL = 2 m
